Pavel Begunkov	a47b255e90	io_uring: add custom opcode hooks on fail ... Sometimes we have to do a little bit of a fixup on a request failuer in io_req_complete_failed(). Add a callback in opdef for that.

Pavel Begunkov	5916943943	io_uring: conditional ->async_data allocation ... There are opcodes that need ->async_data only in some cases and allocation it unconditionally may hurt performance. Add an option to opdef to make move the allocation part from the core io_uring to opcode specific code. Note, we can't just set opdef->async_size to zero because there are other helpers that rely on it, e.g. io_alloc_async_data().

Jens Axboe	d9b57aa3cf	io_uring: move opcode table to opdef.c ... We already have the declarations in opdef.h, move the rest into its own file rather than in the main io_uring.c file. Signed-off-by: Jens Axboe <axboe@kernel.dk>	2022-07-24 18:39:12 -06:00
Jens Axboe	329061d3e2	io_uring: move poll handling into its own file ... Add a io_poll_issue() rather than export the general task_work locking and io_issue_sqe(), and put the io_op_defs definition and structure into a separate header file so that poll can use it.
